N2 - To obtain evident ion current signals which reflect combustion condition in afterburner, areas of high ion concentration need to be identified. Using C12H23 as the fuel species, H3O+, CHO+, COH+, O- and OH- as main ions, total ion concentration and temperature in flame behind a V-gutter flameholder are numerically simulated by realizable κ-ε turbulent model and non-premixed equilibrium chemistry model. Outlet section temperature is in good agreement with experimental data. The results show that distributions of ion concentration and temperature are consistent. There are two areas of high ion concentration: regions of the highest temperature in recirculation zone; regions close to upper and lower edges of flameholder. Peaks of each area appear near the injection holes.
